PHOENIX (KSAZ) - The valley is under a freeze warning Tuesday night; officials urge you to cover your plants and bring any pets inside.
For those that work outside overnight, they are bundling up, but not everyone was prepared for the chill.
In Phoenix the icicles are fake, the ice rink is man-made, and it's no surprise that the chill in the air caught some people by surprise.
Zack Krosky has been working as a valet, parking cars all night and trying to keep warm.
There are heaters all over the Vig, space heaters, and even hanging heaters are keeping the customers cozy.
"As a restaurant with 80% patio it's very important, especially in colder months that we have some backup plan, so we still stay busy, and our customers know they can come enjoy themselves comfortably," said Wesley Heath.
Even at the hostess stand, the heater is in full effect.
"I moved here from Illinois, so I didn't think it was going to be this cold," said Reilly O'Tool.
Visitors and locals alike bundled up as parts of the valley approach freezing temperatures. Still, the cool down has some people learning the hard truth about winters in the desert.
Experts say you should cover outdoor plants, bring pets inside, and cover any exposed pipes as temperatures could hover just above 30 degrees overnight.
